Welcome to the forum

Hypothyroidism is extremely common and causes many different symptoms

Depression and anxiety are extremely common hypothyroid symptoms

List of hypothyroid symptoms

thyroiduk.org/if-you-are-un...

Do you have copies of your actual blood test results and ranges?

50mcg levothyroxine is only a starter dose

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine

Which brand of levothyroxine is your current levothyroxine?

Many people find different brands of levothyroxine are not interchangeable

Important to also have vitamin D, folate, ferritin and B12 levels tested.

Has this been done yet?

Often vitamins are extremely low and improving low vitamin levels by supplementing can help how levothyroxine works

About 90% of primary hypothyroidism is autoimmune thyroid disease also called Hashimoto’s diagnosed by high thyroid antibodies

Has GP tested thyroid antibodies?

Levothyroxine is extremely fussy medication

It must be taken on its own on empty stomach and then nothing apart from water for at least an hour after

No other medications or supplements within 2 hours

Many people find it more convenient to take levothyroxine at bedtime

Levothyroxine is not like an aspirin. No instant change. It takes 2-3 weeks before seeing any improvements

Likely to need several further increases in levothyroxine dose over coming months

Thank you slow dragon its accord. Its so sad I have lost my grandson my son had a baby seven months ago I had a break down couldn't bond with the baby felt flat had a pycotic episode he stated he was fed up with my out bursts. Before the outburst I was having hallucinations our beautiful daughter who is so ill heart op soon to save her life is so angry with them. It was her who put me onto your site it was like a tick box she loves me and always knew something wasn't right in my head and body. Haven't seen my new born grandson for seven months husband diabetic ill man covid shielding him I had a full break down just adds to major stress. So I just put it all down to that .

Stress is the enemy of thyroid

You have a lot on your plate

Be kind to yourself. Rest and recover.

Gentle regular exercise helps

A short walk around the block every day, if you can manage it .....or some yoga

You need to be patient while the levothyroxine slowly improves your metabolism

Make sure GP tests your vitamins too

Sorry I tend to go off still a bit raw Not sure what other tests the doctor did. I asked if he thought it was Hashimotos the reply was I would be a lot more ill if it was!

It almost certainly is autoimmune thyroid disease (about 90% of primary hypothyroidism is autoimmune)

U.K. medics rarely call it hashimoto’s

The best way to get access to current and historic blood test results is to register for online access to your medical record and blood test results

UK GP practices are supposed to offer everyone online access for blood test results. Ring and ask if this is available and apply to do so if possible, if it is you may need "enhanced access" to see blood results.

Link re access

healthunlocked.com/thyroidu...

In reality many GP surgeries do not have blood test results online yet

Alternatively ring receptionist and request printed copies of results. Allow couple of days and then go and pick up.

Important to see exactly what has been tested and equally important what hasn’t been tested yet

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Private tests are available as NHS currently rarely tests Ft3 or thyroid antibodies or all relevant vitamins

guidelines on dose levothyroxine by weight

Even if we frequently don’t start on full replacement dose, most people need to increase levothyroxine dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until eventually on, or near full replacement dose

NICE guidelines on full replacement dose

nice.org.uk/guidance/ng145/...

1.3.6

Consider starting levothyroxine at a dosage of 1.6 micrograms per kilogram of body weight per day (rounded to the nearest 25 micrograms) for adults under 65 with primary hypothyroidism and no history of cardiovascular disease.

Also here

cks.nice.org.uk/topics/hypo...

gp-update.co.uk/Latest-Upda...

Traditionally we have tended to start patients on a low dose of levothyroxine and titrate it up over a period of months. RCT evidence suggests that for the majority of patients this is not necessary and may waste resources.

For patients aged >60y or with ischaemic heart disease, start levothyroxine at 25–50μg daily and titrate up every 3 to 6 weeks as tolerated.

For ALL other patients start at full replacement dose. For most this will equate to 1.6 μg/kg/day (approximately 100μg for a 60kg woman and 125μg for a 75kg man).

If you are starting treatment for subclinical hypothyroidism, this article advises starting at a dose close to the full treatment dose on the basis that it is difficult to assess symptom response unless a therapeutic dose has been trialled.

BMJ also clear on dose required

You could/should get tested at 6-8 weeks after each dose increase in levothyroxine

Plus get GP to include vitamins and thyroid antibodies at next test, if not been tested yet

Meanwhile sign up for online access to your medical record to get the actual results and ranges

Come back with new post once you get these results.

You will need to keep personal records of results, what dose you are taking and how you feel

Can be helpful to write yourself weekly update. That way you can see progress over the weeks

You could test vitamin D now
